Specification of Letters Patent. Patented Sept. 21, 1909- Applicationled June 3, 1909. Serial No. 499,994.

T o all whom it may concern.'

Be it known that I, WILMER W. SALMON, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements ink Railway-Signals, of which the following is a specification.

This invention relates to railway signals.

One object of the invention is to provide a semaphore and spectacles fora signal lamp, that rotate together around the same axis, and areadjustable with reference to each other.

Another object of the invention is a construction whereby the semaphoreand spectacles are independently supported, so that if the semaphorebreaks, the spectacles will still be operative, and if the spectaclebreaks, the semaphore will still be operative.

These and other improvements will be described in the followingspecification and claims.

In the drawings z-Figure 1 is a side View of the casting or frame towhich the blade and spectacles are attached; Figs. 2 and 3 show,respectively, the spectacles and the plate whereby the spectacles aresecured to the operating shaft; Figs. 4-7, inclusive, show in detailseveral different positions in which it is possible to secure thespectacles to the plate, for different locations of the lamp, Fig. 7being an end view, from the right of Fig. 6; and Figs. 8-10, inclusive,show the semaphore and lamp mounted in different positions upon thesupport, and their relative positions when some of the adjustmentsillustrated in Figs. 4-'7, inclusive, are used, Fig. 8 showing twooppositely directed semaphores in position, Fig. 9 being a plan view ofFig. 8, and Fig. 10 showing the adjustments of Figs. 4 and 5 forstaggered lights.

1 is a casting or frame that has at one end a grip 2 for the semaphoreblade, and at the other end 3 is adapted to be attached to its support.The usual blade 4 is attached to the casting by any suitable means, asby bolts 5, but the spectacles 6 are adjustable and so proportioned withreference to the signaling positions of the semaphore that when setcorrectly for the lamp in one signaling position, the other openingswill show the light at its other signaling positions. T o this end thespectacles 6 (Fig. 2) consist of a frame Yor plate that has severalopenings 7, according to the number of signaling positions which thesemaphore is tohave, and these are arranged in an arc whose-center 8coincides with the pivotal center 9 of the semaphore (Fig. 1) when thespectacles are in position. The invention is illustrated in the drawingsby spectacles that are adapted to operate in a single quadrant, and havethree equidistant openings.

The spectacles are not attached directly to the semaphore, but both arerevolubly secured to the operating shaft 13, so that the semaphore andspectacles revolve together around the same axis. A hub 9 on the end 3of the semaphore casting or frame lits nonrevolubly upon the shaft 13,as shown in Fig. 7, and a plate 10 that also lits nonrevolubly upon theshaft 13, as indicated by 11 in Fig. 3, carries the spectacles. Thespectacles are secured to the plate 10 by bolts 14, which pass throughholes 12 in the plate and holes 15 in the spectacles. Four holes 12 areshown, and they are, respectively, represented as equidistant from eachother and also equidistant from the pivotal center of the semaphore, sothat a hole is centrally located in each quadrant of the plate 10. Eightholes 15 are shown around the center 8 of the spectacles, which areequidistant from each other, and at the same radial distance from thecenter as the holes 12. Accordingly, the spectacles can be set aroundthe pivotal center of the semaphore at angular distances apart offorty-five degrees. And since the three openings 7 in the spectacles areangularly forty-live degrees apart, it is possible to accommodate thespectacles to any one of the eight possible positions in which thesignal lamp 16 may be place upon the post or support with reference tothe semaphore blade. While semaphore and spectacles must work in unison,they are independent signals, and this invention makes it possible topreserve their independence and at the same time operate them togetheraround the same pivotal aXis. Thus, the advantages of spectacles locatedat the semaphore are obtained, and at the same time the spectacles arenot disabled by breaking the semaphore. The stud 17 by which theoperating crank and rod (not shown) are attached to the semaphore isriveted in the hole 1S in the,trani@ l, and passes through l adjustablearound the `pivotal vairis of the one of the enlarged holes 19 in thespectacles, 5 semaphore; substantially as shown and deaccording to theirposition on the frame l, l scribed.
